Okay....
So I was thinking..that one of these could be y/n's quirk perhaps? I just really want to get this out of the way, so I can start writing stuff involved with y/n's quirk.
Option 1
Liquid manipulation:💧
Basically y/n can control amything that is a liquid substance water,blood you name it. y/n heat up the liquid until it boils or drop the temperature until it freezes. Kinda like Juvia from Fairy Tail but I dont really want her body to be made out of water.
Drawbacks:the colder they make they water the colder their hands get. Same goes for the other way around, They make the water hot their hands get hotter y/n's muscle also start to tighten after a while.
Option 2
Earth element:🌍
y/n can control plants,sand, dirt, and rocks they can also make mini earthquakes and mini tornados.
Drawbacks:y/n gets headaches, the larger they make the tornados or earthquakes the stronger the headaches get, and the longer they keep their quirk going the more stran they put on their muscles.
